Definitions
- This invention pertains to a handle for concrete and other heavy nonmetallic covers that are buried below grade, such as covers and inspection lids for septic tanks, wells, and concrete and plastic liquid distribution boxes, that provides means for indication of the location of the cover.
- the warning is provided when the excavating machinery catches and draws up a portion of the strip and it is seen by the worker.
- Coding means of a magnetic or radioactive type are applied to the strip before burial of the strip so that once the strip is discovered at the point of excavation, the worker can then determine the subterranean location or run of the utility line by following above ground with suitable sensors, the path of the underground ribbon.
- U.S. Pat. No. 3,916,821 patented by Othmar W. Pies, Nov. 4, 1975 discloses a marker assembly comprising a permanent magnet surrounded by a housing having an upright socket for receiving a stake. When the stake is driven into the ground with the housing below the surface of the ground, the stake can be found from above the ground by a magnetic dipping needle.
- the means for marking comprise an element of the structure.
- the means for marking be light in weight for shipping and storage.
- the means for marking can be made in part from material which is ordinarily discarded at a construction job site.
- the means for marking comprise a plastic handle for a cover of a subterranean structure, and that steel rebar commonly found at a construction job site can be used to complete construction of the plastic handle means for marking.
- a plastic handle for a nonmetallic cover of an element of subterranean installment includes means for receiving by way of insertion a metal marker of substantial mass.
- the means for receiving includes means for holding the metal so that is removable, and the means for receiving has a shape that closely receives rebar.
- FIG. 1 is a vertical perspective view of a handle according to the present invention.
- FIG. 2 is a view of a portion of a handle showing a retaining means.
- FIG. 3 is a vertical perspective view of another handle according to the present invention.
- FIG. 4 is a vertical perspective view of a handle and cover according to the present invention.
- FIG. 5 is a vertical perspective of a handle and cover according to the present invention.
- body 14 of handle 10 is constructed throughout of engineered plastic such as Dupont 801 (tm). It is designed to be gripped by hand, but can be engaged by cable or other lifting means, as the handle can be manufactured to a 2,000 pound rating.
- Legs 18 are designed to be inserted into a concrete, plastic or other nonmetallic cover for an element of construction such as a septic tank, pump chamber, distribution box, and well, that are buried in the ground, in which the cover is buried below grade or below the soil and is out of sight.
- an element of construction such as a septic tank, pump chamber, distribution box, and well
- the handle of the present invention is designed to provide a mark of the location of the cover through use of a metal detector.
- Many metal detector designs which can detect the fully assembled handle below ground are presently available on the market, such as from Radio Shack (tm), a division of Tandy Corp., Fort Worth, Tex.
- Handle 10 includes slot 24 in top 26 of the handle, for receiving a metal bar.
- slot 24 is shaped to receive rebar 32 that is commonly used in construction.
- slot 24 is shaped to receive the rebar by insertion of the rebar from one end of the slot axially into the slot, and to prevent withdrawal of the rebar radially from the slot. A portion of the top therefor extends over each side of the rebar.
- Portions of rebar often abound as scrap on construction sites. Cutting tools for quickly cutting the rebar are also commonly available on construction sites. A portion of rebar is cut preferably to about the length 36 of slot 24, and is inserted into slot 24 at the construction site.
- the handle with rebar provides a high quality marker for detection equipment because the rebar presents to the metal detector a substantially large ferrous mass that is easy to detect for most detectors.
- the handle can be economically molded without the cost in dies and labor of molding-in a remotely detectable marker of the quality of rebar.
- top 40 of a handle of the present invention includes slot 44 which is shaped to receive rebar 32 axially or radially, and to cradle rebar selected from several diameters normally used in construction.
- Retainer means such as rotary catch 46 prevents radial removal of the rebar when the catch is rotated on pivot 48 to a position over the rebar in the slot.
- Handle 50 in FIG. 3 includes retainer pegs 54 which are inserted into slots 56 in side wall 60 of the handle after rebar piece 62 is inserted obliquely into slot 66 in side wall 60.
- Holes 70 in legs 72 hold rebar 76 pieces which increase retention strength of the legs in a cover. Stops 80 help set the depth to which the legs are inserted into the cover when the handle is inserted into the cover material for molding or casting it into the cover.
- handle 84 is mounted in inspection lid 86, and holds rebar 88 behind protrusions 90 of the handle.
- Protrusions 90 yield sufficiently to permit radial insertion of the rebar past the protrusions, into a depression 92 in the handle, and to resist removal of the rebar once so installed.
- handle 94 is bolted to top 96 of cover 98 from below the cover.
- the other cover on the handle is installed in the cover without rebar, as a second handle, as a second marker was needed.
